Severe Weather Coordination Message #1 – Friday 8/9/24 Through Saturday AM 8/10/24 – Severe Weather/Flood Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are possible in Western and Central Massachusetts and Western and Central Connecticut as the remnants of Debby passes to the west of the region. Strong to damaging winds, and heavy downpours leading to urban and poor drainage flooding are the main threats with an isolated weak tornado as a secondary threat with the threat timeframe around 3-11 PM Friday Afternoon and Evening..
..The Storm Prediction Center (SPC) has placed portions of Western/Central Massachusetts and Western/Central Connecticut in a marginal risk for severe weather..
..SKYWARN Self-Activation with Amateur Radio call-up nets will monitor the severe weather potential for late Friday Afternoon and Evening. Pictures and videos of storm damage from the events over the next couple days or prior events in the previous two days can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds and to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..
The remnants of Debby will pass well to the west of Southern New England Friday through Saturday Morning. This means widespread heavy rainfall and flooding is not expected in the region. That said, it puts Southern New England and in particular Western and Central Massachusetts and Western and Central Connecticut at risk for isolated to scattered strong to severe thunderstorms being on the east side of the remnant circulation of Debby. The headlines depict the current thinking. Key factors include:
1.) The conditional straightline wind damage and isolated tornado threat could affect a very localized, spotty area or areas within the severe weather risk area making any impacts hyper localized. In addition, any tornadic circulations maybe very brief or not detectable by radar so severe thunderstorm warnings with tornado possible tags may be utilized more ubiquitously for this event with tornado warnings issued for circulations that can be radar detected and seen for a period of time.
2.) Any flooding that occurs will be localized and typical of severe weather events we see over the course of the summer with urban and poor drainage areas at greatest risk
3.) There will be some general gusty winds of around 40 MPH in gusts with slightly higher gusts in the higher elevations and possibly at the coast that could cause isolated pockets of wind damage.
